Flue Gas Desulfurization System

Paradise Fossil Plant Unit 3, Muhlenberg County, Kentucky

On March 24, 2003, TVA completed an environmental assessment (EA) and issued a finding of no significant impact (FONSI) for the installation and operation of flue gas desulfurization equipment that employs the wet limestone forced oxidation technology to reduce sulfur dioxide (SO2) emissions from Unit 3 at Paradise Fossil Plant. TVA needs to reduce SO2 emissions at Paradise to meet requirements of the 1990 Clean Air Act amendments.

The impacts of the proposed action were found to be insignificant with incorporation of the following two commitments.

Operational and technological controls to meet the limits of the plant’s National Pollutant Discharge Elimination System permit will avoid aquatic toxicity in discharges from the plant.

The use of best management and engineering practices, the elevation or floodproofing of critical system components, and the provision of portable toilets for project construction personnel will ensure that construction-related discharges comply with applicable regulations and executive orders.
